How to Effectively Implement ISA 99 / IEC 62443

ISA 99/IEC 62443

IEC 62443, formerly known as ISA 99, is the worldwide de facto standard for security of industrial control system (ICS) networks. The standard was created by the International Society of Automation (ISA) and was taken over by the International Electrotechnical Commission (IEC), who is responsible for further developing it.

IEC 62443 assists in the evaluation of existing and potential vulnerabilities within ICS and aids in applying the necessary mitigations. The overall goal of this standard is to reduce the risk of threats and failures within ICS networks. The standard consists of 13 documents organized into four groups: General, Policies & Procedures, System and Component.

The following pages list some of the key technical requirements of IEC 62443 and explain how eyeInspect (formerly SilentDefense) helps ICS network operators to comply with them.
